What Is A Heart Murmur?

All of us know, the way our heart works – lub-dub, lub-dub. Even though we consider them heartbeats, they are, in fact, the closing of the valves that control the blood flow in the heart chambers. The heart goes ‘lub’ with the closing of the valves that control blood flow from the upper chambers to the lower chambers. The ‘dub’ happens when the valves controlling blood going out of the heart close.

as it flows through the heart. This sound is called a murmur. If there is turbulence or disturbance in the blood flow through the heart or blood vessels, a murmur may be heard. It is often heard as a whooshing sound between heartbeats. Thus, the ‘lub-dub’ may sound like “lub-shh-dub”. However, the extra sound is simply the sound of normal blood flow moving through a normal heart. It means that even a healthy heart can produce murmurs. These types of murmurs are found in many kids. There isn’t anything to worry about it as their heart works normally.

The doctor may diagnose heart murmurs during a routine check-up. The pediatrician listens to heartbeats using a stethoscope on different areas of the chest. Doctors rate heart murmurs on a scale of 1 to 6 based on how loud they are. While Grade 1 indicates a soft one, Grade 6 shows a loud one.

What Is Wrong If It Is Not An Innocent Murmur?

It can be a sign of a heart problem. An abnormality in the structure of the valves or walls of the heart may lead to some medical complications.

EKG or an echocardiogram, the doctor will evaluate your child’s heart as part of the further examination.

Causes Of Abnormal Heart Murmurs

Valve abnormalities: This happens when the heart valves don’t function normally, disrupting the smooth blood flow. They might be narrow, too thick or too small.

Heart muscle disorders: Because of the abnormal heart muscle, the blood pumping will get affected. The heart muscle might be thick or weak.

Septal defects: A hole in the wall between the heart’s lower chambers affects the functioning of the heart. Small holes may close on their own. But, bigger holes may cause murmurs along with other symptoms.

Worry not, even if your child is diagnosed with a heart problem, treatment is available to cure it. With the advancement of medical science, your doctor will be able to prescribe the most appropriate treatment.
